A cascade synthetic strategy for the direct synthesis of 2-aroyl benzofurans from aryne precursors has been developed. This reaction proceeds via C-O and C-C bond cleavage as well as C-O and C-C bond formation in a single reaction vessel. The methodology provides good yields of 2-aroyl benzofurans and tolerates a variety of functional groups. The synthesized 2-aroyl benzofurans were further benzoylated at 3-positions and one of the synthesized 2,3-diaroyl benzofuran structures was confirmed unambiguously by X-ray crystallography.

An efficient procedure for 2-aroylbenzofuran preparation from 2-bromophenols, phenacyl bromides and paraformaldehyde is described. The cheap and stable paraformaldehyde served as the carbon source via an in situ formylation reaction.
Intramolecular oxidative coupling: I2/TBHP/NaN3-mediated synthesis of benzofuran derivatives
Xu, Wengang,Li, Qingcui,Cao, Chuanpeng,Zhang, Fanglin,Zheng, Hua
, p. 6158 - 6161 (2015/06/08)
A novel intramolecular oxidative coupling reaction has been established to prepare benzofuran derivatives via direct C(sp2)-H functionalization for the formation of C-O bond. This transformation is mediated by I2/TBHP/NaN3 under metal-free conditions and a catalytic amount of NaN3 plays a crucial role in the reaction. Furthermore, the reaction tolerates a broad substrate scope with average to excellent yields.

scheme or table, p. 1436 - 1442 (2012/03/09)
Aromatic ketones were efficiently prepared in good yields by the reactions of aryl bromides with n-BuLi, followed by the reactions with aromatic aldehydes or aliphatic aldehydes and the subsequent treatment with molecular iodine and K2CO3, in a one-pot method. The same treatment of arenes, instead of aromatic bromides, also provided the corresponding aromatic ketones in good yields. Using these methods, various diaryl ketones and alkyl aryl ketones bearing electron-rich aromatics and electron-deficient aromatics could be prepared efficiently by a simple, transition-metal-free, and therefore environmentally benign experimental procedure.
